A scientific controversy as to whether X‐ray diffraction line broadening, associated with cold‐worked metals, was due to break‐up of the metal crystals into minute crystallites or due to lattice strain is recalled, with reference to an abortive attempt by Sir Lawrence Bragg to reconcile the opposing views. Subsequent studies have shown how balanced Sir Lawrence's judgment of the problem was.
